Abstract

Abstract : Diels–Alder-reactions of a thiazol-2-thione-based, tricyclic 1, 4-diphosphinine were investigated, showing that the central aromatic π-system can react with various dienophiles. In one case, photochemical deprotection of the 1, 4-diphosphinine was found. Abstract : Diels–Alder-reactions of a thiazol-2-thione-based, tricyclic 1, 4-di-phosphinine were investigated, showing that the central aromatic π-system can react with various dienophiles. The reaction with 4-phenyl-1, 2, 4-triazoline-3, 5-dione was special as the product revealed a remarkable sensitivity towards light, thus enabling the photochemical deprotection of the tricyclic 1, 4-diphosphinine.
